PT. Lentera Bumi Nusantara merupakan pusat penelitian turbin angin yang dikembangkan di daerah Cipatujah, Kabupaten Tasikmalaya. Ditempat ini  pengembangan sumber energi alam menjadi pusat penelitian, salah satunya yaitu sumber energi listrik angin. Fokus pengembangannya yaitu Pembangkit Listrik Tenaga Bayu skala micro yang diberi nama Wind Luce (YWS-500) disebut juga A-WING. Kontrol sistem charging pembangkit listrik tenaga bayu ini masih dalam tahap pengembangan, dikarenakan dalam kontrol sistem charging untuk baterai masih menggunakan sistem manual yaitu melakukan pengukuran secara langsung ke tempat menggunakan  alat ukur digital dan pencatatan. Sehingga, permasalahan yang harus di selesaikan yaitu bagaimana memperoleh data kontrol sistem charging pada baterai dan dapat diakses melalui jarak jauh secara realtime. Metode yang digunakan pada penelitian ini yaitu studi literatur, obsevasi, perancangan sistem, pengumpulan kebutuhan sistem, pengujian unit, perakitan sistem, pengujian sistem, dan menganalisis hasil pengujian. Proses kontrol sistem charging  pada pembangkit listrik tenaga bayu ini untuk memperoleh data baterai melalui jarak jauh secara realtime menggunakan sistem online yang terhubung dengan jaringan internet atau menggunakan Internet of Things (IoT) yang nantinya data dapat diketahui dengan mudah. Hasil dari pengujian kontrol sistem charging ini memiliki nilai maksimum dan minimum pada setiap besaran listrik yang terukur oleh kontrol sistem charging. Pada charging measurement mempunyai nilai tegangan maksimum sebesar 26,65 Volt dan minimumnya sebesar 23,92 Volt sedangkan nilai charging current maksimum sebesar 7,77Ampere. Kemudian untuk charging power memiliki 3 nilai yaitu nilai Average Charging Wattage 24,48 Watt, nilai Maximum Charging Wattage 206,15 Watt dan Obtained Power 587,32 wh. Kontrol  ini dapat memperoleh data kontrol sistem charging pada baterai wind turbine secara realtime melalui jarak jauh. Sehingga, pembuatan kontrol sistem charging ini  lebih memudahkan dalam melakukan kontrol pada baterai dengan tampilan yang disajikan pada website dan display LCD, dengan menggunakan ESP32 sebagai pengolah data serta sebagai  penghubung ke jaringan internet.

Turbine Drive

The wind turbine drive system is one of the key components in converting wind energy into electrical energy. The life prediction of drive system is very important for the maintenance of wind turbine. With increasing capacity, the wind turbine system has become more complicated. Consequently, for the life prediction of drive system, it is necessary to consider the problems of multi-information fusion of big data, quantification of time-varying dynamic loads, and analysis of multiple-damage coupling. In order to solve the above challenges, the fatigue life analysis and evaluation method considering the interaction of coupled multiple damages are proposed in this study. The hierarchical Bayesian theory with fault physics technology is introduced to deal with the uncertainty of wind turbine drive system. Then, a time-varying performance analysis model is established based on the multiple-damage coupling competition failure mechanism. Moreover, the Internet of Things (IoT) technology is introduced and combined with the proposed model. Through the data collection by IoT, the time-stress curve of drive system can be obtained. A case study about the remaining fatigue life estimation of drive system is utilized to illustrate the effectiveness of the proposed method.

The Internet Of Things

The existing stand-alone multimedia machines and online multimedia machines in the market have certain deficiencies, so they cannot meet the actual needs. Based on this, this research combines the actual needs to design and implement a multi-media system based on the Internet of Things and cloud service platform. Moreover, through in-depth research on the MQTT protocol, this study proposes a message encryption verification scheme for the MQTT protocol, which can solve the problem of low message security in the Internet of Things communication to a certain extent. In addition, through research on the fusion technology of the Internet of Things and artificial intelligence, this research designs scheme to provide a LightGBM intelligent prediction module interface, MQTT message middleware, device management system, intelligent prediction and push interface for the cloud platform. Finally, this research completes the design and implementation of the cloud platform and tests the function and performance of the built multimedia system database. The research results show that the multimedia database constructed in this paper has good performance.
